That doesn't surprise me because TCP allows to acknowledge multiple received packets/frames at once, sends out multiple frames before waiting for an acknowledge, ... If you need acknowledges just use TCP. I had to implement some "safe" data delivery in UDP (because the other end was a microcontroller without TCP implementation) and it really is no fun. /Tobias -- NOA Audio Solutions Vertriebsges. m.b.H.
